The Lumenier Digital RBG Arm LED board is a universal addressible array of RBG LEDs. The board has 4 super bright RBG LEDs installed that can work directly with the Lumenier RGB LED Tail or to a flight controller with Cleanflight LED control software. The LEDs need 5v, ground and a signal source in order to work.
The Layout of the PCB board keeps wiring clean and neat with input and output pads on the same end of the board. This way each arm on your aircraft can have a LED board with the wiring pointing to the middle.
